feat: 升级Gemini服务使用TolerantJsonParser进行JSON解析
- 集成tolerant_json_parser.rs到GeminiService中 - 替换原有的正则匹配JSON提取逻辑 - 使用Arc<Mutex<TolerantJsonParser>>支持Clone trait - 改进错误处理和日志输出，包含解析统计信息 - 添加回退机制，当TolerantJsonParser失败时使用传统方法 - 更新所有GeminiService::new()调用点处理Result返回类型 - 添加全面的测试用例验证新的JSON解析逻辑 - 保持API向后兼容性，方法签名不变 遵循promptx/tauri-desktop-app-expert开发规范
